VENTILATING ATTACHMENT POR WINDOWS.'

SPECIFICATION arming part of Letters Patent No. 637,187, dated November 14, 189e; Application filed July 6, 1899. Serial No. 722,950. (No model.)

To all whom t may con/cern.:

Be it known that I, GEORGE M. WAGNER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveinvented a new and Improved Ventilating Attachment for Windows, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, durable, and economic attachment to windows, whereby one or more panes may be quickly and simultaneously entirely removed from the main sash and securely held in a position enabling them' to be conveniently and expeditiously closed, thus affording perfect ventilation.

A further object of the invention is to secure ventilation without objectionable draft and to so construct the attachment that it will be especially adapted to all forms of windows having prism glass, the attachment serving to keep the prisms in the same position when opened as when closed, thus obtaining the full beneiit of the deflected light.

Another` object of the invention is to provide a Ventilating device that will open inward instead of outward,l as usual, being thereby protected by the window-framework and permitting the use of -bars or screens outside of the window.

A further object of the invention is to provide a fluid-tight connection between the littings `or frames of the movable panes and those of the fixed panes.

The invention consists in the novel construction and combinations of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front .elevation of a window having the improved Ventilating device applied thereto. Fig. 2 is a vertical longitudinal section taken practically on the line 2 2 of Fig. 1, showing the Ventilating attachment closed in positive lines and open in dotted lines; and Fig. 3 is a transverse section taken practically on the line 3 3 of Fig. 1.

The window-frame A' may be of any desired construction, as likewise the windows sash A', fitted to the frame. The said sash comprises the usual upper and lower mein.- bers and lland side members 12, together` with cross-bars 13, in which the glass panes 14. are secured in any desired manner. Sundry of the panes of glass, however, are adapted to be removed entirely from the sash A", in the drawings the upper and lower panes being so adapted, but each alternate pane vmay be made removable, if desired. The removable panes 14a are provided with a frame 13a, in which they are fitted, and usually the upper members o f the said frames 13a are provided with a slanting concaved upper surface 15 and the lower member with a slant ing conveXed lower surface 16, and these slanting concaved and conveXed surfaces are adapted to t snugly to mating surfaces 17, formed on the iixed cross-bars 13 of the sash A and the under edge of the top and the uph per edge of the bottom members when the removable panes 14 are at the top and bottom of the sash. By bringing the frames of the removable panes thus .in practically interlocking engagement with opposing surfaces of the sash A' joints are obtained that are fluid-tight and through which rain cannot pass even in a beating storm.

The frames 13a of the removable panesleta are secured to side bars 18, preferably of metal, the attachment being made in any desired way. The side bars 18 are preferably provided with a fork 19 at their upper ends, and in each fork 19 the lower end of a downwardly-curved arm 2O vis pivotally attached, the upper ends of which arms 20 are pivoted between ears formed upon plates 2l. The plates 21 are preferably tted in recesses produced instrips 23, which may be ornamental or otherwise, attached to the outer face of the window-sash at the top, the ears of the plates 21 extending inwardly through openings 22 in the sash; but the plates 21 may be secured directly to the inner faces of the upper member of the sash, if desired, or other provision may be made for their application to the sash.

The lower portions of the side bars 18 are pivotally attached to the lower ends of a second set of downwardly-curved arms 24., which arms at their opposite ends are pivoted between ears formed upon plates 25, and these plates 25 are shown as iitted in recesses in a reinforcing-strip 27, located at the outer face IOO of the lower member 1l of the -sash A, as shown in Fig. 2, the ears of the plates 25 extending inwardly through openings 2G in the sash. The lower portions ofthe side bars 18 are preferably connected by a bar 28, and a locking device is provided for the side bars, adapted to hold them either out of engagement with the window-sash or in engagement therewith. This locking device consists usually of an upwardly-curved fixed arm 29, that extends through an opening 3l inthe lower member of the window-sash, as shown in Fig. 2, the plate 30, to which the locking-arm 29 is secured, being fitted in the reinforcingstrip 27. One of the side bars 18 of the movable frame is longer than the other and terminates in a loop 32, througlrwhich loop the locking-arm 29 is passed, and a set-screw 33 is carried by this loop, adapted for engagement with the said locking-arm, as shown in Figs. l and 2.

When the removable panes are in position in the sash, the movable frame, consisting of the side bars 18 and cross-bar 2S, rests against the inner face of the sash and in no manner mars the appearance of the window. Vhen ventilation is required, the set-screw 33 is loosened and the movable frame 18 is carried outward and upward parallel with the sash and fixed panes. In this manner the movable panes carried by the movable frames are withdrawn from the sash A', permitting ample ventilation, but the movable panes still remain vertical, so that the efect of ornamentations on the said movable panes is not interfered with or in the slightest degree destroyed. v

In addition to the advantages mentioned in the preamble of this specitication it may be stated that the attachment is especially suited to church-windows and all other fixed glass windows and will secure Ventilation without destroying the effect of the design. Likewise the construction of the attachmentfacilitates closing the movable panes in the event of the sudden approach of a storm, as all of the movable panes are simultaneously brought in locking position in the sash A, as they are likewise simultaneously carried from the sash. As stated, the curved joints render almost impossible the chance of rain or water finding ingress, making the window practically weather-proof. liurthermore, the attachment is exceedingly simple in all of its working parts and is adaptable to all styles of windows.

Having thus described my invention, I

claim as new and desire to secure by Letters Patentl. A window -sash having sundry of its panes in frames removably fitted in said sash, said frames having beveled surfaces for engaging with corresponding surfaces on the sash, andan operating mechanism for the said framed panes, arranged to conduct the panes to and from the sash.

2. A window-sash provided with a series of fixed panes and a movable pane, the movable pane being provided with an independent frame arranged for fluid-tight engagement with the framing of the window-sash, a carrier attached to the removable frame, and curved arms connected with the sash and with the ends of the carrier, the arms being curved in the same direction, as described.

3. A window-sash provided with fixed panes and removable panes, the removable panes having independent frames,which frames are provided with inclined surfaces at the lop and bottom, adapted to meet similarly-inclined surfaces in the framing of the said sash, downwardly-cu rved arms pivotally connected with the sash and located at the inner face of the said sash at the top and at the bottom, and side bars pivotally attached to the top and bottom arms, said side bars being likewise secured to the frames of the removable panes, as specified.

et. A window-sash provided with fixed panes and panes removable from the sash, the removable panes having independent frames, which frames are provided with inclined surfaces at the top and bottom, adapted to meet similarly-inclined surfaces in the framing of the said sash, downwardly-curved arms pivotally connected with the sash and located at the inner face of said sash at the top and at the bottom, side'bars pivotally attached to the top and bottom arms, said side bars being likewise secured to the frames of the removable panes, and a locking device for the-said side bars.

5. A window-sash provided with movable panes and a carrier pivotally connected with the sash and connected with the said movable panes, the carrier and the frames of the panes being arranged to move in parallel lines and at right angles to the plane of the sash to and from the said sash, as set forth.
